'CONVERTIBLE COMBINATION' COAL AND GAS RANGE.

Application' mea June 7, 1920., seriai No. 387,245;

To all 107mm t may concern .j

Be it known that l, EDWARD C.. Bilans, a citizen of the United States,l residing at Rochester, in the .county of ll/ionroe and State of New'York, have invented certain new and useful .improvements in Convertible Combination Coal andGasRanges, of' which the following is a specification."

This invention relates mainly to that class of convertible coal and gas ranges having a single oyemwhich maybe Vheated with solid fuel only. gaseous fuel only, or by using both fuels at the same time. Vln this type of range, as at present constructed, the baking oven is necessarily placed adjacent to the solid fuel lire-box, and is immovable therefrom. The heating of this oven with gaseous fuels has resulted invariably in many objectionable results and faulty constructions, owing to the restricted spaces for, and consequent undesirable location yof the burners. ln certain types of these/ranges the burners are positioned in the oven and more or less cumbersome baffle plates, partitions, vent fines and ducts are used'to distribute the heat throughout the oven. These parts not only change the shape and reduce the size of the oven but must be heated, with consequent waste of fuel, before the oven can be brought to the'baking temperature. Furthermore, complicated mechanism is provided to fold or raise these burners, plates', dempers, etc., from the floor, or away from the walls of the oven, when the latter is t0 be heated with solid fuel-fwhere they remain to not only obstruct theoven, but again be heated with a consequentwaste of fuel. If the removal of these parts by hand is required (many times when hot) the operator is discouraged and at a loss to know what to do with them.

ln other types of these ovens the burners and their boxes or partitions, are posi-l tioned in the coal fines of the range, adjacent to the oven, where theyobstruct the free circulation of the products of combustion when solid fuel is used, thereby causingthe ovenV to bakeslowly and unevenly-in manycases it is necessary to light the gaseous fuelburners to complete the 'operation of baking@ Burners placed in coal flues are diicult to speciaeauon of Lenersratent.

light, clean and replace. Many times theyvv are not adequately supplied with'air toprevent flames being smothered undercertain conditions. A -multiplicity' of push rods, cranks and coge, designed' to openvandfclose dampers, fluesand' vents are also undesirable features in thatrthej'f tend to confuse the op-l erator, are liable to get out'of order, and'if not properly adjusted and maintained, will defeat the Very purpose for which they were designed. Y

It `is, obvious from the foregoing that the drawbacks 1n the present construction of convertible ovens, as applied to combination coal and gas; ranges, are largely due to the vfixedA positionv of the oven and faulty location of'the gaseous fuel'burners, and that these and many other defects,- can be eliminated by making the'wall of theoven movable (when it is desired to `heat the oven with gaseous fuel) to a place adj acentto theburner, the latter being positioned in a location where it cannot obstructithe solid fuel fines, or oven.'

' yOne object of my invention is `the eliminathereof v'partially broken away to showjthe oven and the fluesof the range in section.

F ig, 1 0 is a longitudinal sectional view of another modified form of my invention. I ln the several figures ofthe drawings, like reference numerals indicate like parts. The construction of the convertible oven for combination coal and range is illustrated in the accompanying drawings in which reference numeral indicates the frame of the range. 0n the left hand side of the frame is located the fire box 2 from `which leads the flue 3 over the top of the oven t and down on the right hand side thereof to the bottom of the oven.` `The products of combustion vfrom the lire in the fire box 2 pass through the iue 3 over thel top of the oven l, down on the right hand side thereof to the bottom of the oven where they are deiiected bythe battle" plate to the front of the bottom of the oven prior to their escape into the chimney 6. v

The oven 4 has a frame 7 mounted to move enuwise therein. This rame coinpi'ises the left hand wall 8 and 'the right hand wall 9 which form the right and lef walls proper of the oven. The'lcft hand wall and the right hand wall are connected at the top and the bottom by means of the parallel cross rails i9, 10.

The oven body it in which the frame 7 is mounted is cut away at the right in order to permit the right hand wall 9 of the frame to move out therefrom. The right hand wall 9 hasran opening 11 provided in the middle thereof' in which the plate 12 is mounted to swing. This plate 12 has flue stripl-B Vformed on either side thereof, which iiue strips together with the plate 12 form a convertible coal and gas `flue as will presently appear. The plate 12 is pivoted at thebottom of the frame 7 and extends up into the inside of the frame 7 and slightly overlaps a portion of the inside of the the purpose of limiting the movement of the plate 12 toward the inside of the frame 7.

The movement of the plate 12 against the inside of the wall 9 is limited by the contact of the plate with the inside of the pory down the right hand end thereof and under the bottom from where they pass out into the chimney 6. This course taken by these gases and its heating effect on thevoven ,4 is the saine as in most of the modern sheet flue ranges that are now in use. The gases are unobstructed in their travel through the flue until they pass out into the chimney.

The space between the right hand wall 9 of the ovenrl and the outer right hand wall 17 ofthe ranoe forming part ofthe vertical flue is divided by the partition 18. VThis partition has an opening 19 provided therein in which the swinging plate 20 is mounted. The opening 19 and the swingingplate 2O 'which forms a. doortherefor is located in the partition 18 at a point opposite to the opening in the right hand Wall 9 and its swinging door 12.V

The vertical flue 21 formed by the parti` tion 18 and the right end plate 17 is again divided by n pair of flue strips 22, 22, which divide the vertical fine 21 into a central, 'vertical flue 23' and two other smaller vertical flues 24, 24, on either side thereof. In thefeentral vertical flue 23 and adjacent to the bottom of the opening 19 in the partition 18 is mounted the gas burner 25. This burner 25 separates a small portion of the lower part of the central flue 23. Leading out from the lower part of this sepa rated portion of the flue 23 is an opening 26 in front of which is provided the angular dedecting plate 27. The gas burner 25 is provided with burner holes both in the top and in the bottom so that both the top part of the central flue as well as'the bottom part thereof can be heated thereby, independently of each other. To provide the necessary air for the combustion of the gases from 'the burner 2,5, a door 27A is mounted in the right end plate 17 of the range. This .door opens in front of the 'i ier 25 so that it can be easily lighted ,riir to both the top andbottom ofthe burner through suitable openings in thedoorl n When the is to be converted for the purpose of heating the oven 4 by means of ethi'ough'and at the' same time furnishes the gas vburner 25 either alone or together with the products of combustion from the 'reibox 2,v the frame 7 lwith its left and right hand walls 8 and l9, respectively, together' with the plate 12 and flue strips 13, 13,-are moved to the right. ln so doing the flue strips 13 of the plate 12 are moved intol the opening 19 in the partition 1:8. When these flue strips enter vthe opening 19 the swinging door 2O is pushed inwardly while at the same time the plate 12 on which the fine strips 13 are formed is tilted into the interior of the oven. In Fig. l3 the oven is shown before the frame 7 is moved and in Fig. 5 the oven is shown after the movement has beencoIn-y pleted.- After the frame 7 has been moved,

the plate 12 is tilted into the oven and the plate 20 is tilted into the central flue 23, the plate 2O rests on top of the fluestrips 13 of the plate 12 and thus forms a convertible flue that is inclosed on allsides and lleads from the top of the gas burner 25 to the inside of the oven Vand the frame 7. The flue thus formed is adapted to convey the products of combustion from the gas burner 25 to the inside of the oven. From the inside of the oven, the products of combustion pass out through the opening 2S near the top of the left hand wall 8. lhen the frame 7 has been moved to the right as previously described, a small iue 28A is formed in back of the left. hand wall andthe products of combustion passing through vthe opening 28 enter this liuc and then pass out through the .opening 29 in the bottom of the fi'ue thus formed into the flue 3 under the oven, from where they pass out into the chimney 6. The prod-` ucts of combustion from the top of the burner 25 which pass through the oven to heat the inside thereof, also heat a portion of the bottoni of the oven fronirthe outside beginning at the point Where they pass through the opening 29 and enter the flue 3.

' The4 products of combustion which are given off from the bottom of the burner 25 pass out through the opening 26 and are deflected by the baille plate 27 to the flue 3 under the oven in which they travel until they also pass out into the chimney 6. The products of combustion. from the underside of the burner 25 heat the wholeof the bot-- they pass out through the chimney. Thus, p

the das burner 25 heats the'oven se aratel e P from both the inside and the outside thereof and this without interfering with the free circulation of the products of combustion from the fire boX.

Vhile the oven is being heated from the' gas burner, the products of combustion from the fire boX circulate without obstruction around the oven except at the right handfend thereof, At this point, instead of traveling throughl .the vertical. flue 3 at the right y,side

' the to of combustion enter` the auxiliary vertical flues, 24,124, `on either sideof the central ue 23 in which the gas burner 25 is located. the bottom of `these Lf lues 24, 24, the products of combustion4 pass out through the openings 31, 31, inthe partition 18, and enter into the flue 43 -on the under sideof the oven, `as do the products of combustion from the bottom of the gas burner25.` z

. In thefevent` ,where the range contains a ire in the tire box, and itpis desired' to heat the oven by gaseous fuel,the products of combustion from thefrebox 2 are notobstructed in their passage to. the .chimney 6 as they 'travel through th e. flue k3 Voverthe top ofthe oven 4 and then downwardly through the auxiliary v{lues-24, 24, `and .at the point where they leave .the openings 31 in the auxliaryefiues 24, the products of combustiony mix with the products of combustion" from vthe undersideof the'gas burner 25. v l

From1this'point,all. of the products of combustion from the several fuels pass under the oven along the flue 3 until. they vmeet the products ofcombustion from thetop of the gas burner 25 below the opening 29 before they enter the; exitinto lthe chimney 6. In this way, the products of combustion from the fire boXassistthe products of combustion from the bu'rnerf25 in heating the oven Without waste of heat from either the ltire boX or the burner. vIt will'also be apparent from an inspectionv of Figs. 3 and 5 that, no matter what fuel is used to heat the oven, vthe prdd.- ucts of combustion from the fire box as well as those from the burners heat thejoven Yon all sides thereof.V In order to prevent the products of comi` bustion from the top of the "gas burnervfrom entering the inside of ',the oven a false top 30 may be suspendedna short distance below ofthe oven proper., rl`his forms a flue'in the top of the oven in which they products of combustion from the gas burner are conveyed .fromthe outside of theright handA ,wall `to :the outside'of the left hand wall of the oven i withouty passi-ng into 'the oven proper. This is shown. in Fig. 7. V In Fig. 91 have shown'a modification fof the oven andv the gas burners for heating same. In this form, a second lgas burner32 is placed at the left hand end of the oven below ythe opening 29. The products of combustion-from this burner pass through the opening 29 into the Vflue 28A and from there n through the opening 28 into theinterior ofv the oven 4. At the same timethat the productsof combustion enter theoven through the opening 28 at the upper left hand corner of the oven,the products'of combustionfrom the burner 25 enter lthe oven at the top o f the right hand. corner ofthe ove11. The prodf c ucts of .combustion from both .ofithe burners burner mounted in said compartment, means to conduct the products of combustion from said burner in lsaid compartment to said oven, a'second Vgas burner, means to conduct the products of combustion from said seo-Vv ond gas burner-,into said oven at a point opposite to the entranee of the products of al1 of the products of combustion*from''bothk 10 v of said gas burners from said oven. In testlmony whereof I aX my slgnatllre.
